The rendering engine is an engine for rendering a drawing that needs to be displayed or printed. The display range information is used for determining the geographical range of the power grid geographical edge layout to be displayed. And the layer information is the power grid information which is used for determining the power grid geographical edge layout and needs to be displayed. As shown in fig. 3, the grid geographical edge layout is a grid geographical edge layout with geographical information such as an electronic map or a satellite image as a background, and the grid geographical edge layout includes geographical location information and grid related information. The power grid GIS client is a client of a power grid GIS system, the power grid GIS system is composed of the power grid GIS client and a server, and the power grid GIS system is a production management comprehensive information system which connects power equipment, a transformer substation, a power transmission and distribution network, power users, power loads and the like of a power enterprise to form power informatization.

And step S280, rendering the grid vector slice map by using the grid slice map as a background through the rendering engine according to the preset primitive icon definition, so that the grid vector slice map is superposed into the grid slice map.
The preset primitive icon definition refers to the corresponding relation between the grid vector slice and the grid equipment or lines, and is used for determining the meaning represented by the grid vector slice.

When a new area is browsed or a new attribute label is switched and selected, the graphs and the label characters in the current picture are displayed by adding one piece for several seconds until all the graphs and the label characters are displayed.
According to the power grid geographical edge layout display method, when a user inputs a power grid geographical edge layout needing to be displayed at a client side of a terminal display power grid geographical edge layout, the client side calls a spatial index function to obtain a power grid vector slice map and a grid slice map through a rendering engine according to obtained display range information and layer information, and the rendering engine of the client side enables the power grid vector slice map to be superimposed on the grid slice map according to preset primitive icon definitions; calling a labeling engine to label and draw the grid vector slice map superposed in the grid slice map, starting to display the grid slice map by a display interface when the grid slice map is obtained, and further updating the display content of the display interface in real time according to the rendering progress so that the rendered grid vector slice map is displayed in real time on the basis of the grid slice map by the current display interface; and updating the display content of the display interface in real time according to the annotation drawing progress, and displaying the drawn annotation in real time.

In one embodiment, the step of calling a spatial index function to obtain a grid vector slice map and a grid slice map according to the display range information and the layer information includes:
calling a spatial index function to obtain a power grid vector slice image according to the display range information and the layer information and a preset obtaining mode; and calling a spatial index function to acquire the grid slice map from the local memory and/or the server according to the display range information, wherein the priority of acquiring the grid slice map from the local memory is higher than that of acquiring the grid slice map from the server.

And calling a spatial index function to acquire the grid slice map from the local memory and/or the server according to the display range information, specifically, determining a geographical area to be displayed according to the display range information, calling the spatial index function to index the grid slice map corresponding to the geographical area from the local memory of the terminal, and when the local memory of the terminal does not have the grid slice map, sending an acquisition instruction of the grid slice map corresponding to the geographical area to the server to acquire the corresponding grid slice map.
The preset acquisition mode of the power grid vector slice image comprises the following steps: the first acquisition mode is as follows: calling a spatial index function to acquire a power grid vector slice image from a client memory according to the display range information and the layer information; the second acquisition mode is as follows: calling a spatial index function to acquire a power grid vector slice image from a local memory according to the display range information and the layer information; the third acquisition mode is as follows: calling a spatial index function to obtain a power grid vector slice diagram from a server according to the display range information and the layer information; the priority of the first acquisition mode is higher than that of the second acquisition mode, and the second acquisition mode is higher than that of the third acquisition mode.

The memory of the client is limited by the size of the memory, the upper limit of the cache is set to be about 100MB to 500MB, and only the recently accessed and browsed power grid vector slice image is cached. During storage, the grid vector slice images are stored separately according to different types of the grid vector slice images, and caching is performed in a mode of separate, multiple or one-time transmission of the different types of the grid vector slice images. The power grid graph and topology data adopt a vector picture form, and are gradually accumulated and cached at a client; the in-station diagram, the single line diagram and the system wiring diagram are uniformly in the form of SVG pictures and are downloaded and stored from the server at one time; the attribute data (the attribute data comprises attributes, parameters, running states and the like of the grid vector slice image) are acquired to the client for caching when a plurality of attributes needing to be displayed are acquired; and the analysis data is integrally acquired to the client for caching by taking the data partition as a unit.
The local memory is affected by the available space of the disk and can cache several GB of data. After the client is started, the data to be accessed is quickly loaded into the memory of the client from the local memory without accessing a server. The local memory cache needs double encryption, the first encryption encrypts the directory and the file name, and the second encryption encrypts the content of the data file.

Specifically, the method comprises the following steps: the map component, the SVG graph component, the power grid graph component and the dynamic coloring component of the rendering engine are defined according to a preset graphic primitive icon, control parameters such as layer visibility, icon size and whether a label is displayed or not are obtained by calling a GwksView interface display window and a GTopoDisplaypara method, coordinate transformation from the window to the map is obtained by calling a GDispXfm method, a coordinate transformation matrix is carried out by using a coordinate transformation matrix GTransformStack method, then a viewport GVIewport method is called, and a corresponding layer is drawn according to a GBlock method and a derivative thereof.

For the substation resource Gadget, a drawing symbol of the substation map layer needs to be inquired from the map layer display control parameter GTopoDisplayPara method, and a GGadgetDefBlock method is called for drawing. For the linear vector electronic map object GGISLineString method, a worldDraw method of a linear geometric object GChain method of the base class is called for drawing.
In one embodiment, the step of calling the annotation engine to perform annotation drawing on the grid vector slice map rendered into the grid slice map comprises the following steps: and calling a labeling engine to label and draw the grid vector slice map rendered into the grid slice map based on a space rule avoiding algorithm.

And marking and drawing the grid vector slice map rendered into the grid slice map according to the drawing position determined by the space rule avoiding algorithm.
